What you have to remember here is that Her Majesty's Gov't especially Theresa May and David (Knob in a Pig) Cameron can't even spell "internet" let alone being able to draft any coherent legislation to control the Internet.
This is more from the UK Gov't's Department of Sound Bites for the Newspapers Agency. It will never happen because they don't understand the scale of the problem or the massive bucket of data they'd need the ISP to hold and we all know that GCHQ are doing this stuff already. They also don't reveal that most ISPs want to remain as carrier only and not collectors of their customer's data (except Talk Talk who already collect it just so they can let the hackers steal it).

That's quite simply because the public school twat is 100% clueless when it comes to any new tech.

His cabinet friends are equally 100% clueless.

And his gov't advisers are too clueless to tell the clueles twats that they're clueless twats.

It would be nice if we get a Gov't on May 7th that isn't formed by a bunch of clueless twats but we won't. They teach them how to be clueless twats when they do their PPE degrees at Oxford and gain entry to the Establishment. It's the first rule of being a member of the UK Parliament and part of the UK Gov't.
